Abstract: A dual working airgap force motor has a centrally located stator (10) includes two toroidally shaped electromagnets (26, 28) with the axis of the stator (10) coinciding with the axis of the toroids. Each toroidal coil (26, 28) is separated from the other toroidal coil (28, 26) by an axial distance. Toroidal permanent magnets (18A, 18B) are also mounted preferably inside the toroidal electromagnet coils (26, 28) and also spaced apart axially. The permanent magnets generate a flux flow in opposite axial directions whereas, upon energisation, the toroidal coils generate flux flow in the same axial direction at a given radial position. Two armatures (14A, 14B) are located on an output shaft (16) at either end of the stator (10) and each armature is spaced apart from the stator by inner and outer axial airgaps (22A, 22B, 24A, 24B). Energisation of the coils (26, 28) with current causes a greater flux flow across the inner and outer airgaps at one end than is caused through the inner and outer airgaps at the other end, thus tending to reduce the airgap at the end with the largest flux flow and consequently causing movement of the respective armatures (14A, 14B) and the output shaft (16) upon which they are mounted.

Abstract: Efficient coupling between an optoelectronic device (13) and an optical fiber (15) is obtained by using different monocrystalline elements of different crystallographic orientation for mounting, respectively, the fiber and the optoelectronic device. For example, the crystallographic orientation of an upper monocrystalline element (17) is chosen such that a horizontal groove (20) for supporting the optical fiber and a reflecting surface (19) for directing light into the fiber may both be made by anisotropic etching. The crystallographic orientation of a lower monocrystalline silicon element is chosen such that appropriate etching will yield a mounting surface (23) for the optoelectronic device (13) which is suitable for directing light from the reflecting surface (19) into the optical fiber (15) with maximum efficiency. 
     In one illustrative embodiment, the upper monocrystalline element (17) is {100} silicon, and the lower monocrystalline element (18) is {112} silicon. As will be explained more fully later, this permits anisotropic etching so as to form a  V -groove (20) that supports a horizontally-extending optic fiber, a reflecting surface (19) that extends at 54.74°, and a support surface (23) for the optoelectronic device that extends at 19.48° with respect to the horizontal. These relative angles provide for optimum optical coupling between the optoelectronic device and the optical fiber, while providing horizontal surfaces for supporting both electronic circuitry and the optical fiber, as is desired for secure packaging and integration of the package apparatus into a lightwave communications system.

Abstract: A machine for taper threading the end of a bar (21) such as reinforcing bar used in concrete construction utilizes a power operated vice (40) to clamp and feed the bar end axially into a rotary head (42) which contains chaser tooling holders (116-119) which open uniformly on the bar end as the head rotates. The rotary head is axially stationary but contains an axially movable key or linear cam (134) which engages a readily removable transversely extending control rod assembly (127) in turn moving the chaser holders. Axial movement of the power vice and thus the bar end at a controlled axial speed with respect to the rotary speed of the head moves the key to cause the movement of the chaser holders. The chaser holders in addition to supporting the thread cutting chasers (181) also support ahead of the chaser an indexable triangular insert (180) to pre-cone the bar end. To change the set-up of the machine for different bar sizes the control rod is removed and replaced, and a proper cutting speed for the bar is selected by adjusting the RPM of the head through a transmission. The extent of axial movement of the key may also be controlled to optimize the cycle time of the machine. In this manner all bar sizes may be threaded in a single pass and set-up from bar size to bar size is accomplished quite simply in a short period of time.

Abstract: At the transmit end of a video communications system, a first motion vector is derived from successive frames during a frame transmit mode and a second motion vector is derived during or immediately following a frame discard mode. An interframe predicted error signal is generated which is representative of the difference between each input frame and a motion-compensated, previous frame during the frame transmit mode, the difference being zero during the frame discard mode. The predicted error signal and the vectors are transmitted to the receive end of the system. In a first embodiment, the second motion vector is derived at the transmit end from frames spaced apart by a discarded frame, and at the receive end, original frames are recovered from the predicted error signal as well as from the first and second motion vectors, and the second motion vector is down-scaled and evaluated whether it is valid or not. During frame discard mode, motion compensation is performed on the recovered frame using the down-scaled vector in response to a valid evaluation, but no compensation is performed if invalid evaluation is made. In a second embodiment, the second motion vector is derived at the transmit end from successive frames using a larger block size than that used in the first motion vector. At the receive end, the first motion vector as well as the error signal are used in recovering original frames. During the frame discard mode, the second vector is simply used for motion compensation.
